Arc Rupture is a Magnificent and terrible spell.
When you cast it, Four 2 foot diameter spheres of lightning leap from your outstretched hand, then streak in straight lines to spots you select. Each sphere leaves a jagged path of lightning behind it.

If you aim the spheres at a specific creature, you must make a ranged touch attack against that creature.
Any creature struck by the spheres take 2d6 sonic damage and must make a Fortitude save or become dazed. Creatures struck directly by Arc Rupture are denied a reflex save.
You may aim more than one sphere at the same target.
Once a sphere reaches its destination, it explodes in a 40-foot-radius spread, dealing 6d6 points of electric damage to each creature in the area, dealing half damage on a sucessful reflex save.
If a creature is within the area of more than one sphere, it must save separately against each.
(electric resistance applies to each sphere's damage individually).
